Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of differential pressure coating machines, in particular to a reaction chamber with differential pressure template shaping function, a differential pressure coating machine and a coating method. BACKGROUND

[0002] The differential pressure coating machine (also known as vacuum suction machine or film coating machine) is a surface treatment machine that uses the principles of heat softening and pressure difference (positive pressure and negative pressure) to tightly and seamlessly cover the surface of various irregular surfaces or flat substrates (such as furniture boards) with thin film materials (such as PVC film).

[0003] The related technologies of the differential pressure coating machine are as follows:

[0004] 1. Chinese invention patent application, invention name: differential pressure coating machine, patent application number: CN202210947088.2;

[0005] 2. Chinese invention patent application, invention name: differential pressure coating machine alternating use recovery cooling high pressure gas system and control method, patent application number: CN202511187187.5;

[0006] 3. Chinese utility model patent application, utility model name: cooling structure of differential pressure coating machine, patent application number: 202521639155X;

[0007] 4. Chinese utility model patent application, utility model name: workbench device cooling structure of differential pressure coating machine and differential pressure coating machine thereof, patent application number: 2025216391564;

[0008] At present, the working principle of the differential pressure coating machine on the market is as follows:

[0009] S1, the reaction chamber and the workbench are set, the film jig is located in the middle of the upper reaction chamber and the lower reaction chamber, the film jig separates the upper reaction chamber and the lower reaction chamber into two closed spaces that do not communicate with each other, and the product jig is located inside the lower reaction chamber;

[0010] S2, vacuum suction is performed on the upper reaction chamber and the lower reaction chamber respectively, so that the upper reaction chamber and the lower reaction chamber respectively present a certain negative pressure environment state;

[0011] S3, the first heating assembly and the second heating assembly are started respectively, the first heating assembly heats the upper reaction chamber and the film jig respectively, and the second heating assembly heats the product jig;

[0012] S4, when the film jig reaches the specified heating temperature, the product jig is driven to abut against the bottom of the film jig, so that the product abuts against the bottom of the film;

[0013] S5, high pressure gas is introduced into the upper reaction chamber, so that the negative pressure environment state of the upper reaction chamber is converted into a high pressure environment state;

[0014] Therefore, due to the pressure difference between the high pressure environment state of the upper reaction chamber and the negative pressure environment state of the lower reaction chamber, the high pressure gas of the upper reaction chamber will press the heated film into the product, thereby realizing the product coating work.

[0015] However, during the operation of the differential pressure coating machine described above, it is found that after coating by the differential pressure coating machine, there are still individual convex points (small points similar to sharp and hard), individual small bubble protrusions (small points similar to round bubbles), and individual dark point color differences (the point is relatively dark, which may be due to the fact that the point is not firmly attached, resulting in a dark color of the point) between the product and the film. As society continues to develop and people's material living standards continue to improve, people's quality requirements for industrial products are becoming higher and higher. This phenomenon is currently recognized in the industry as a production defect of the differential pressure coating machine, a poor coating quality phenomenon, and cannot meet the delivery requirements.

[0016] The mechanism behind this phenomenon may be that during the process of introducing high pressure gas into the upper reaction chamber, the high pressure gas presses the film into the product. At this time, when the high pressure gas covers the glue on the film, the high pressure gas is not uniformly stressed on the top surface of the film (the high pressure gas is in disordered motion, and the more the film is not flat, the more unevenly the film is stressed. At the same time, the glue is free-flowing between the film and the product, and these unstable factors may cause the high pressure gas pressure to be uneven). Because the high pressure gas pressure is not uniform, the direction of the free-flowing glue is not fixed, ultimately causing the high pressure gas pressure at some points of the film to be insufficient, resulting in some points not being firmly attached, some points being squeezed by the glue around them to form convex points or bubble protrusions, and thus causing the product surface to form convex points, bubble protrusions, and points not being firmly attached, resulting in color differences (the point is relatively dark).

[0017] Therefore, as described above, the current differential pressure coating machine still has the problem of surface defects such as individual convex points, small bubble protrusions, and dark color differences on the product surface after coating, thereby resulting in insufficient product neatness, insufficient aesthetics, and failure to meet product yield.

[0060] Example One

[0061] Please refer to Figures 2 to 15Embodiment 1 of the present invention provides a reaction chamber with a differential pressure template shaping function, comprising a reaction chamber shell 100, on which a high-pressure gas delivery assembly and a vacuum pumping assembly 104 are respectively installed. An upper reaction chamber 11 and a lower reaction chamber 12 located at the bottom of the upper reaction chamber 11 are respectively opened inside the reaction chamber shell 100. The upper reaction chamber 11 and the lower reaction chamber 12 are respectively connected to the vacuum pumping assembly 104. A first heating assembly 106 is installed on the upper reaction chamber 11, and the upper reaction chamber 11 is connected to the high-pressure delivery assembly. The invention also includes a differential pressure template shaping assembly 13, which includes a rotating assembly 131 mounted on the upper reaction chamber 11 and... A shaping template 133 is mounted on the rotating assembly 131. One end of the shaping template 133 corresponds to the shape of the membrane of the membrane fixture 23. A vacuum extraction channel 132 connected to the vacuum extraction assembly 104 is opened inside the shaping template 133. A second vacuum port 134 connected to the vacuum extraction channel 132 is opened at one end of the shaping template 133. The rotating assembly 131 drives the shaping template 133 to rotate away from the bottom of the upper reaction chamber 11 or to rotate closer to the bottom of the upper reaction chamber 11. When the rotating assembly 131 drives the shaping template 133 to rotate closer to the bottom of the upper reaction chamber 11, the shaping template 133 is used to press into the membrane of the membrane fixture 23 and realize differential pressure shaping of the membrane.

[0062] The vacuum pumping assembly 104 is a vacuum pump. First vacuum ports 102 are respectively opened on the upper reaction chamber 11 and the lower reaction chamber 12. The vacuum pump is connected to the first vacuum ports 102. A high-pressure gas tank (not shown in the attached drawing) is located on one side of the reaction chamber shell 100. The high-pressure gas delivery assembly is a high-pressure gas pump (not shown in the attached drawing). A high-pressure gas port 105 is opened at one end of the upper reaction chamber 11. The high-pressure gas tank, high-pressure gas pump, and high-pressure gas port 105 are sequentially connected. The vacuum pump is also connected to a second vacuum port 134. The vacuum pump is connected to both the first vacuum port 102 and the second vacuum port 134 via a vacuum pipeline (not shown in the attached drawing). The high-pressure gas pump is connected to the high-pressure gas port 105 via a gas delivery pipeline (not shown in the attached drawing). A vacuum storage tank (not shown in the attached drawing) is located on one side of the reaction chamber shell 100. The vacuum storage tank supplies gas to the vacuum pump for pumping and storage, or the vacuum pump directly pumps gas and discharges it to the external environment.

[0063] The first heating assembly 106 includes an upper heating pipe 1061 installed on the top of the upper reaction chamber 11 and / or a side heating pipe 1062 installed on the surrounding side walls of the upper reaction chamber 11.

[0064] The upper heating tube 1061 and the upper reaction cavity 11 top are provided with a reflective sheet, and the side heating tube 1062 and the upper reaction cavity 11 are provided with a reflective sheet around the side wall, the reflective sheet is used to make the upper heating tube 1061 and the side heating tube 1062 radiate heat to the whole upper reaction cavity 11 and the bottom of the upper reaction cavity 11, so that the upper reaction cavity 11 is heated more uniformly.

[0065] Please refer to Figures 9-15 The differential pressure template shaping assembly 13 has the following four embodiments:

[0066] As Figures 9-10 The first embodiment of the differential pressure template shaping assembly 13 is as follows:

[0067] The rotating assembly 131 includes a lifting drive module 1311 arranged on the reaction chamber shell 100, and a lifting drive rod 13110 is arranged on the lifting drive module 1311, the lifting drive rod 13110 penetrates one end of the reaction chamber shell 100 and enters the upper reaction cavity 11, and a lifting connecting rod 13111 is hinged at one end of the lifting drive rod 13110, and the lifting connecting rod 13111 is hinged at one end of the shaping template 133, and the bottom of the upper reaction cavity 11 is provided with an annular frame 1313, the shape of the annular frame 1313 corresponds to the outer contour shape of the diaphragm jig 23, and a fixed hinge support 1314 is arranged on the annular frame 1313, and the fixed hinge support 1314 is hinged with the shaping template 133.

[0068] The working principle of the above-mentioned first embodiment is as follows: in the running state of the differential pressure template shaping assembly 13, the lifting drive module 1311 of the rotating assembly 131 drives the lifting drive rod 13110 to move downward, and the lifting drive rod 13110 drives the lifting connecting rod 13111 to press downward, and because the shaping template 133 is hinged with the fixed hinge support 1314, one of the shaping template 133 is pressed downward by the lifting connecting rod 13111, and the other of the shaping template 133 rotates downward around the fixed hinge support 1314, so that the whole shaping template 133 rotates downward, and finally the shaping template 133 rotates close to the bottom of the upper reaction cavity 11, and the shaping template 133 is used for pressing into the diaphragm of the diaphragm jig 23 and realizing differential pressure shaping of the diaphragm; conversely, the lifting drive module 1311 goes up-> the lifting drive rod 13110 goes up-> the lifting connecting rod 13111 goes up-> the shaping template 133 rotates upward around the fixed hinge support 1314-> the shaping template 133 rotates away from the bottom of the upper reaction cavity 11, and in the next differential pressure coating, the shaping template 133 avoids blocking the heating of the first heating assembly 106 to the upper reaction cavity 11 and the diaphragm of the diaphragm jig 23.

[0069] For example, the first embodiment of the differential pressure template shaping assembly 13 is divided into the following two examples:

Figure 4 The fact that two lifting drive modules 1311 are set in the middle is only to improve stability; in reality... Figure 4 (A single lifting drive module 1311 can also be used). Two lifting linkages 13111, shaping templates 133, and annular frames 1313 are used. The lifting drive module 1311 is installed in the middle of the reaction chamber shell 100. The lifting drive rod 13110 and fixed hinge support 1314 are installed in the middle of the upper reaction chamber 11. The lifting linkage 13111, shaping template 133, and annular frame 1313 are respectively installed on both sides of the upper reaction chamber 11; or, as... Figure 9 As shown, when the number of differential pressure template shaping components 13 is set to two, the number of lifting drive modules 1311, lifting drive rods 13110, lifting connecting rods 13111, shaping templates 133, and annular frames 1313 are also set to two. The lifting drive modules 1311 are respectively installed on both sides of the reaction chamber shell 100, and the lifting drive rods 13110, lifting connecting rods 13111, shaping templates 133, annular frames 1313, and fixed hinge supports 1314 are respectively installed on both sides of the upper reaction chamber 11.

[0073] like Figure 11 As shown, the second embodiment of the differential pressure template shaping component 13 is as follows: the rotating component 131 includes a lifting drive module 1311 mounted on the reaction chamber shell 100, a lifting drive rod 13110 mounted on the lifting drive module 1311, the lifting drive rod 13110 passing through one end of the reaction chamber shell 100 and entering the upper reaction chamber 11, a fixed motor 1315 mounted on one or both sides of one end of the lifting drive rod 13110, a hinge arm 1316 mounted on the rotating shaft of the fixed motor 1315, and the shaping template 133 mounted on the hinge arm 1316.

[0074] The working principle of the second embodiment is as follows: in the running state of the differential pressure template shaping assembly 13, the rotating shaft of the fixed motor 1315 of the rotating assembly 131 is driven to rotate the articulated arm 1316, the articulated arm 1316 drives the shaping template 133 to rotate, the shaping template 133 changes from a vertical state to a horizontal state, the lifting driving module 1311 drives the lifting driving rod 13110 to move downward, the lifting driving rod 13110 drives the shaping template 133 to move downward, until the shaping template 133 is close to the bottom of the upper reaction cavity 11, and the shaping template 133 is used to press into the diaphragm of the diaphragm jig 23 and realize differential pressure shaping of the diaphragm; conversely, the lifting driving module 1311 moves upward -> the lifting driving rod 13110 moves upward -> the shaping template 133 moves upward, so that the shaping template 133 is away from the bottom of the upper reaction cavity 11 -> the rotating shaft of the fixed motor 1315 rotates -> the articulated arm 1316 rotates -> the shaping template 133 changes from the horizontal state to the vertical state,

[0075] In the next differential pressure film coating, the shaping template 133 avoids blocking the first heating assembly 106 from heating the upper reaction cavity 11 and the diaphragm of the diaphragm jig 23.

[0076] As shown in Figure 12 and 13 The third embodiment of the differential pressure template shaping assembly 13 is as follows: the rotating assembly 131 includes a lifting driving module 1311 installed on the reaction chamber shell 100, the lifting driving module 1311 is installed with a lifting driving rod 13110, the lifting driving rod 13110 penetrates one end of the reaction chamber shell 100 and enters the upper reaction cavity 11, one end of the lifting driving rod 13110 is hinged with a lifting connecting rod 13111, one end of the lifting connecting rod 13111 is hinged with the shaping template 133, one side of the lifting driving module 1311 is installed with an auxiliary lifting module 1312, the auxiliary lifting module 1312 is installed with a displacement lifting rod 13120, the displacement lifting rod 13120 penetrates one end of the reaction chamber shell 100 and enters the upper reaction cavity 11, one end of the displacement lifting rod 13120 is installed with a displacement plate 13121, the displacement plate 13121 is installed with a fixed hinge seat 1314, and the fixed hinge seat 1314 is hinged with the shaping template 133.

[0077] The first working principle of the third embodiment is as follows (first down and then rotate): in the running state of the differential pressure template shaping assembly 13, the lifting driving module 1311 of the rotating assembly 131 drives the lifting driving rod 13110 and the auxiliary lifting module 1312 drives the displacement lifting rod 13120 to synchronously descend, so that the shaping template 133, the displacement plate 13121 and the fixed hinged seat 1314 synchronously descend. When the displacement plate 13121 reaches the bottom of the upper reaction cavity 11, at this time, the auxiliary lifting module 1312 stops driving the displacement lifting rod 13120, so that the displacement plate 13121 is located at the bottom of the upper reaction cavity 11. (At this time, the displacement plate 13121 can be suspended and stationary, can be placed on the diaphragm jig 23 and stationary, or an annular frame 1313 can be additionally arranged and stationary by being placed on the annular frame 1313.) At this time, the lifting driving module 1311 continues to drive the lifting driving rod 13110 downward, and the lifting driving rod 13110 drives the lifting connecting rod 13111 downward. Since the shaping template 133 is hinged to the fixed hinged seat 1314, one part of the shaping template 133 is pressed downward by the lifting connecting rod 13111, and the other part of the shaping template 133 rotates downward around the fixed hinged seat 1314, so that the shaping template 133 rotates downward as a whole, and finally the shaping template 133 rotates close to the bottom of the upper reaction cavity 11, and the shaping template 133 is used for pressing on the diaphragm of the diaphragm jig 23 and realizing differential pressure shaping of the diaphragm. Conversely, the lifting driving module 1311 goes up-> the lifting driving rod 13110 goes up-> the lifting connecting rod 13111 goes up-> the shaping template 133 rotates upward around the fixed hinged seat 1314-> the lifting driving module 1311 and the auxiliary lifting module 1312 synchronously go up-> the lifting driving rod 13110 and the displacement lifting rod 13120 synchronously go up-> the shaping template 133, the displacement plate 13121 and the fixed hinged seat 1314 synchronously rise, the shaping template 133 rotates away from the bottom of the upper reaction cavity 11, and in the next differential pressure coating, the shaping template 133 avoids blocking the first heating assembly 106 from heating the upper reaction cavity 11 and the diaphragm of the diaphragm jig 23.

[0078] The second working principle of the third embodiment is (turning first and then lowering): in the running state of the differential pressure template shaping assembly 13, the lifting driving module 1311 of the rotating assembly 131 drives the lifting driving rod 13110 to descend, and the auxiliary lifting module 1312 stops. Since the shaping template 133 is hinged to the fixed hinge support 1314, one of the shaping template 133 is pressed downward by the lifting connecting rod 13111, and the other of the shaping template 133 rotates downward around the fixed hinge support 1314, so that the shaping template 133 rotates downward as a whole, and the shaping template 133 is in a horizontal state. Then, the lifting driving module 1311 drives the lifting driving rod 13110, and the auxiliary lifting module 1312 drives the displacement lifting rod 13120 to descend synchronously, so that the shaping template 133, the displacement plate 13121, and the fixed hinge seat 1314 descend synchronously. When the displacement plate 13121 reaches the bottom of the upper reaction chamber 11, the shaping template 133 is close to the bottom of the upper reaction chamber 11, and the shaping template 133 is used to press on the diaphragm of the diaphragm jig 23 and realize differential pressure shaping of the diaphragm. Conversely, the lifting driving module 1311 and the auxiliary lifting module 1312 are synchronously upward -> the lifting driving rod 13110 and the displacement lifting rod 13120 are synchronously upward -> the shaping template 133, the displacement plate 13121, and the fixed hinge seat 1314 are synchronously upward to a certain position -> the lifting driving module 1311 drives the lifting driving rod 13110 upward, and the auxiliary lifting module 1312 stops -> the shaping template 133 rotates upward around the fixed hinge support 1314, and finally the shaping template 133 rotates away from the bottom of the upper reaction chamber 11. When the next differential pressure coating is performed, the shaping template 133 avoids blocking the first heating assembly 106 from heating the upper reaction chamber 11 and the diaphragm of the diaphragm jig 23.

[0079] As Figure 14 and 15As shown, the fourth embodiment of the differential pressure template sizing assembly 13 is: the rotating assembly 131 includes two lifting drive modules 1311 respectively arranged on the two sides of the reaction chamber shell 100, two lifting drive modules 1311 are respectively provided with lifting drive rods 13110, two lifting drive rods 13110 respectively pass through one end of the reaction chamber shell 100 and enter the upper reaction cavity 11, one end of the two lifting drive rods 13110 is respectively hinged with the two sides of the sizing template 133, one side of the reaction cavity 11 is provided with a first rotating track rail 1317, and the other side is provided with a second rotating track rail 1318, one side of the sizing template 133 is slidingly connected to the first rotating track rail 1317, and the other side is slidingly connected to the second rotating track rail 1318, the first rotating track rail 1317 includes a first vertical sliding rail 13171 and a first 1 / 4 circular rail 13172 connected to one end of the first vertical sliding rail 13171, and the second rotating track rail 1318 includes a second vertical sliding rail 13181 and a second 1 / 4 circular rail 13182 connected to one end of the second vertical sliding rail 13181, the first 1 / 4 circular rail 13172 is located at the bottom of the second 1 / 4 circular rail 13182, and the first 1 / 4 circular rail 13172 is arranged opposite to the second 1 / 4 circular rail 13182.

[0080] The working principle of the fourth embodiment is as follows: in the initial state of the differential pressure template shaping assembly 13, the initial state of the shaping template 133 is that the shaping template 133 is in a vertical state, one end of the shaping template 133 is located at the bottom end of the first 1 / 4 circular track 13172, and the other end is located at the highest end of the second 1 / 4 circular track 13182; in the running state of the differential pressure template shaping assembly 13, the lifting drive module 1311 of the rotating assembly 131 drives the lifting drive rod 13110 to press downward, the shaping template 133 first rotates along the first 1 / 4 circular track 13172 and the second 1 / 4 circular track 13182 to change from the vertical state to the horizontal state, specifically, because one end of the lifting drive rod 13110 is hinged to the shaping template 133, and because the lifting drive rod 13110 presses downward on the shaping template 133, the shaping template 133 rotates, so that one end of the shaping template 133 rotates from the bottom end of the first 1 / 4 circular track 13172 to the highest end of the first 1 / 4 circular track 13172, and correspondingly, the other end of the shaping template 133 rotates from the highest end of the second 1 / 4 circular track 13182 to the bottom end of the second 1 / 4 circular track 13182, so that the highest end of the first 1 / 4 circular track 13172 is flush with the bottom end of the second 1 / 4 circular track 13182, thereby realizing that the shaping template 133 is in a horizontal state; then the shaping template 133 descends along the first vertical slide rail 13171 and the second vertical slide rail 13181 to reach the bottom of the upper reaction chamber 11, and the shaping template 133 is used to press into the diaphragm of the diaphragm jig 23 and realize differential pressure shaping of the diaphragm. Conversely, the lifting drive module 1311 goes up-> the lifting drive rod 13110 goes up-> the shaping template 133 goes up along the first vertical slide rail 13171 and the second vertical slide rail 13181-> when one end of the shaping template 133 reaches the highest end of the first 1 / 4 circular track 13172 and the bottom end of the second 1 / 4 circular track 13182-> the lifting drive rod 13110 is pressed upward-> one end of the shaping template 133 rotates along the highest end of the first 1 / 4 circular track 13172 to the bottom end of the first 1 / 4 circular track 13172, and the other end rotates along the bottom end of the second 1 / 4 circular track 13182 to the highest end of the second 1 / 4 circular track 13182.

[0081] Wherein, the above-mentioned lifting drive module 1311 and auxiliary lifting module 1312 are respectively lifting cylinders, in addition, the above-mentioned lifting drive module 1311 and auxiliary lifting module 1312 can also be a combination of a sliding table or a cylinder, a slide rail and a slide block (or a guide rod and a bushing), or a combination of a rotary motor, a synchronous wheel and a synchronous belt, a slide rail and a slide block, or a combination of a rotary motor, a lead screw and a slide block, or other driving assemblies that drive in a straight line.

[0082] The shaping template 133 includes a mounting plate 1331 and a shaping plate 1332 installed at one end of the mounting plate 1331, a vacuum suction passage 132 is opened in the mounting plate 1331, a differential pressure mold cavity 1333 is opened at one end of the shaping plate 1332, a second vacuum air port 134 is opened on the differential pressure mold cavity 1333, and the differential pressure mold cavity 1333 corresponds to the diaphragm shape on the diaphragm jig 23. The vacuum suction passage 132 is manufactured as prior art, and its manufacturing method is described in Chinese invention patent application, invention name: differential pressure coating machine, patent application number: CN202210947088.2, which will not be repeated here.

[0083] The shaping plate 1332 is a silica gel material component, and the number of the second vacuum air port 134 is at least one. When the number of the second vacuum air port 134 is one, the second vacuum air port 134 is opened in the middle of the differential pressure mold cavity 1333. When the number of the second vacuum air port 134 is two, the second vacuum air port 134 is opened on both sides of the differential pressure mold cavity 1333. The shaping plate 1332 is made of silica gel material component, which can ensure that the shaping template 133 is used for pressing into the diaphragm on the diaphragm jig 23 and realizes the differential pressure shaping process of the diaphragm, and ensures that the gap between the shaping plate 1332 and the diaphragm is isolated from the high-pressure gas environment of the upper reaction cavity 11, thereby ensuring the vacuum degree of vacuumizing between the shaping plate 1332 and the diaphragm in the subsequent step. Of course, the shaping plate 1332 can also be made of plastic material, metal material and the like, but when the shaping plate 1332 is made of plastic material, metal material and the like, the shaping plate 1332 needs to have very high machining precision.

[0092] S2: The vacuum air extraction assembly 104 respectively performs vacuum air extraction on the upper reaction cavity 11 and the lower reaction cavity 12, so that the upper reaction cavity 11 and the lower reaction cavity 12 are in a certain negative pressure environment state, at this time, the vacuum air extraction assembly 104 is closed;

[0093] S3: In the initial state of the differential pressure mold plate shaping assembly 13, the rotating assembly 131 drives the shaping mold plate 133 to rotate away from the bottom of the upper reaction cavity 11, so that the shaping mold plate 133 does not block the area of the bottom of the upper reaction cavity 11, at this time, the first heating assembly 106 and the second heating assembly are started respectively, the first heating assembly 106 is used for heating the upper reaction cavity 11 and the diaphragm jig 23, and the second heating assembly is used for heating the product jig 22;

[0094] S4: The temperature measuring sensor is used for measuring the temperature of the diaphragm on the diaphragm jig 23, when the diaphragm reaches the specified temperature, the second lifting device 4 drives the product jig 22 to abut against the bottom of the diaphragm jig 23, so that the product abuts against the bottom of the diaphragm;

[0095] S5: The high-pressure gas delivery assembly introduces high-pressure gas into the upper reaction cavity 11, so that the upper reaction cavity 11 changes from the negative pressure environment state to the high-pressure environment state, because the high-pressure environment state of the upper reaction cavity 11 and the negative pressure environment state of the lower reaction cavity 12 form a pressure difference, so that the high-pressure gas of the upper reaction cavity 11 presses the diaphragm tightly on the product;

[0096] S6: The upper reaction cavity 11 is kept for a certain time, and when the time reaches, the high-pressure gas delivery assembly is closed;

[0097] S7: In the running state of the differential pressure template shaping assembly 13, the rotating assembly 131 drives the shaping template 133 to rotate and approach the bottom of the upper reaction cavity 11, so that the differential pressure cavity 1333 of the shaping template 133 abuts on the diaphragm of the diaphragm jig 23, the vacuum pumping assembly 104 pumps the vacuum pumping channel 132, the vacuum pumping channel 132 pumps the second vacuum air port 134, the second vacuum air port 134 pumps the space between the differential pressure cavity 1333 and the diaphragm, so that the space between the differential pressure cavity 1333 and the diaphragm is in a certain negative pressure environment, and because of the pressure difference between the high-pressure environment of the upper reaction cavity 11 and the negative pressure environment of the space between the differential pressure cavity 1333 and the diaphragm, the high-pressure gas of the upper reaction cavity 11 will press the shaping template 133 tightly on the diaphragm.

[0098] The technical advantages of the coating method of the differential pressure coating machine of the third embodiment of the present application are that the diaphragm is pressed into the product based on the high-pressure gas of the upper reaction cavity 11, and then the characteristics of the high-pressure gas are fully utilized, the differential pressure template shaping assembly 13 and the above step S6 are matched with the high-pressure gas, so that the shaping template 133 corresponds to the diaphragm shape and is pressed in, and then the pressure difference between the high-pressure gas and the vacuum negative pressure between the shaping template 133 and the diaphragm is formed, which pushes the shaping template 133 to be uniformly pressed on the diaphragm, and the pressing force is stronger, so as to further ensure that the glue between the diaphragm and the product is uniformly stressed, and the glue at some convex point positions, small bubble positions, and color difference dark positions is further extruded and flattened, so as to avoid defects such as convex points, small bubble protrusions, and color difference darkness on the product surface, thereby ensuring the yield, appearance, and cleanliness of the product.

10. A differential pressure coating machine, characterized in that, It includes a reaction chamber (1) with pressure differential template shaping function as described in any one of claims 1-9, wherein a temperature sensor is installed on the reaction chamber (1) through the reaction chamber shell (100) and into the upper reaction chamber (11), a first lifting device (3) for driving the reaction chamber (1) to reciprocate up and down is installed on the reaction chamber (1), a workbench (2) is installed below the reaction chamber (1), a mold (21) is installed on the workbench (2), a product fixture (22) is installed above the mold (21), a diaphragm fixture (23) is installed above the product fixture (22), a second lifting device (4) is installed at the bottom of the mold (21), the second lifting device (4) is used to drive the product fixture (22) to reciprocate away from or abut against the bottom of the diaphragm fixture (23), and a second heating component is installed inside the product fixture (22).

11. A coating method using a differential pressure coating machine, characterized in that, It is achieved by a differential pressure coating machine as described in claim 10, which includes the following steps: S1: The first lifting device (3) drives the reaction chamber (1) to move downward, so that the reaction chamber (1) and the workbench (2) are molded together, so that the mold plate (21) of the workbench (2) abuts against the bottom of the lower reaction chamber (12) of the reaction chamber (1), so that the upper reaction chamber (11) and the lower reaction chamber (12) are respectively in a closed state, so that the membrane fixture (23) is located between the upper reaction chamber (11) and the lower reaction chamber (12), and so that the product fixture (22) is located inside the lower reaction chamber (12). The membrane fixture (23) separates the upper reaction chamber (11) and the lower reaction chamber (12) into two independent areas that are not connected to each other. S2: The vacuum pumping assembly (104) performs vacuum pumping on the upper reaction chamber (11) and the lower reaction chamber (12) respectively, so that the upper reaction chamber (11) and the lower reaction chamber (12) are respectively in a certain negative pressure environment. At this time, the vacuum pumping assembly (104) is turned off. S3: In the initial state of the differential pressure template shaping assembly (13), the rotating assembly (131) drives the shaping template (133) to rotate away from the bottom of the upper reaction chamber (11), so that the shaping template (133) does not block the bottom area of ​​the upper reaction chamber (11). At this time, the first heating assembly (106) and the second heating assembly are activated respectively. The first heating assembly (106) is used to heat the upper reaction chamber (11) and the membrane fixture (23), and the second heating assembly is used to heat the product fixture (22). S4: The temperature sensor is used to measure the temperature of the diaphragm on the diaphragm fixture (23). When the diaphragm reaches the specified temperature, the second lifting device (4) drives the product fixture (22) to abut against the bottom of the diaphragm fixture (23), so that the product abuts against the bottom of the diaphragm. S5: The high-pressure gas delivery assembly introduces high-pressure gas into the upper reaction chamber (11), so that the upper reaction chamber (11) changes from a negative pressure environment state to a high pressure environment state. Since the high pressure environment state of the upper reaction chamber (11) and the negative pressure environment state of the lower reaction chamber (12) form a pressure difference, the high pressure gas in the upper reaction chamber (11) presses the diaphragm onto the product. S6: Keep the upper reaction chamber (11) warm and pressurized for a certain period of time. After a certain period of time, turn off the high-pressure gas delivery component. S7: When the differential pressure template shaping assembly (13) is in operation, the rotating assembly (131) drives the shaping template (133) to rotate and approach the bottom of the upper reaction chamber (11), so that the differential pressure mold cavity (1333) of the shaping template (133) abuts against the diaphragm of the diaphragm fixture (23). The vacuum pumping assembly (104) pumps air from the vacuum pumping channel (132), the vacuum pumping channel (132) pumps air from the second vacuum port (134), and the second vacuum port (134) pumps air from the space between the differential pressure mold cavity (1333) and the diaphragm, so that the space between the differential pressure mold cavity (1333) and the diaphragm is in a certain negative pressure environment. Since the high pressure environment of the upper reaction chamber (11) and the negative pressure environment of the space between the differential pressure mold cavity (1333) and the diaphragm form a pressure difference, the high pressure gas of the upper reaction chamber (11) presses the shaping template (133) tightly onto the diaphragm.
